Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pad box which is one of the components of eyeglasses, and more particularly to a pad box for attaching a nose pad to a pad arm planted from a frame.
[0002]
[Prior art]
A pad box, which has a saddle shape and accommodates the tip of the leg of the nose pad inside and pivotally supports it, is an important component of the glasses, but in general, the pad box is a pad array implanted from the spectacle frame. -It is brazed to the tip of the arm, and it was structurally impossible to change the positional relationship with the pad arm.
[0003]
[Problems to be solved by the invention]
The nose pad supported by the pad box is an important part that fits the glasses to the nose of the eyeglass user, and the position of the nose of each eyeglass user that is not the same as one person in order to obtain a good wearing feeling, It is essential to fine-tune the position according to the dimensions. At this time, it is relatively easy to move the nose pad back and forth, left and right with respect to the spectacle frame body by re-bending the pad arm, but it is difficult to move the pad up and down. In retail stores, this vertical repositioning was almost impossible.
[0004]
In particular, in the bifocal glasses, it is necessary to finely adjust the vertical position of the lens, but it is not easy to finely adjust the vertical position at the technical level of general eyeglass retailers. Many cases are handed over and worn. As a result of studying a mechanism that can easily change and adjust the vertical position of the noise pad, the present inventor has made the pad box that pivotally supports the noise pad moveable with respect to the pad arm. The present inventors have succeeded in enabling the adjustment of the vertical position and propose the mechanism as the present invention.
[0005]
[Means for Solving the Problems]
It forms a saddle shape consisting of four peripheral wall surfaces 2a, 2b, 2c, 2d adjacent to each other, one bottom surface 3 and an opening 4, and is located near the opening 4 between a pair of opposed peripheral walls 2a, 2c. Position near the bottom surface 3 with respect to the nose pad leg pivot screw 7 between the pair of peripheral wall surfaces 2b, 2d adjacent to the peripheral wall surfaces 2a, 2c of the pad box body 1 to which the nose pad leg pivot screw 7 is attached. A pad arm insertion hole 10 through which the pad arm 9 can be inserted is provided, and slits 12 are respectively provided from the inner side edge of the pad arm insertion hole 10 toward the opening 4, and 4 adjacent to each other. Two peripheral wall surfaces 2 a ′, 2 b ′, 2 c ′, 2 d ′ are formed into a bowl shape composed of one bottom surface 3 ′ and an opening 4, and a nose pad leg pivot between a pair of opposed peripheral wall surfaces 2 a ′, 2 c ′. Pad box body with support screw 7 A pad arm insertion groove 14 through which a pad arm 9 can be inserted is formed at a position near the bottom surface 3 of a pair of peripheral wall surfaces 2b 'and 2d' adjacent to the bottom surface 3 'and the peripheral wall surfaces 2a' and 2c '; By providing the slit 15 from the side edge of one peripheral wall surface 2b 'or 2d' in contact with the pad arm insertion groove 14 toward the opening 4, the above-mentioned problem is solved.

DETAILED DESCRIPTION OF THE INVENTION
1 is an enlarged perspective view of a first embodiment of a pad box according to the present invention, and FIG. 2 is a front view of the pad box as viewed from the direction of arrow A in FIG. FIG. 3 is a plan view seen from the direction of arrow B in FIG. In the figure, reference numeral 1 denotes a pad box main body, which has a bowl shape composed of four peripheral wall surfaces 2 a, 2 b, 2 c, 2 d adjacent to each other, one bottom surface 3, and an opening 4. As shown in FIG. 3, a nose pad leg pivot screw 7 pivotally supports the tip of the leg 6 of the nose pad 5 at a position near the opening 4 between the pair of opposed peripheral wall surfaces 2a and 2c. Installed. In the figure, reference numeral 8 denotes a female screw portion opened in the peripheral wall surface 2c in order to be screwed into the nose pad leg pivot screw 7.
[0007]
Similarly, as shown in FIG. 3, pad pads are located at positions near the bottom surface 3 with respect to the nose pad leg pivot screw 7 between the pair of peripheral wall surfaces 2 b and 2 d adjacent to the peripheral wall surfaces 2 a and ac, respectively. A pad arm insertion hole 10 through which the arm 9 can be inserted is provided. In this embodiment, since the pad arm 9 has a square cross section, the pad arm insertion hole 10 also has a corresponding square shape. Further, slits 12 are respectively provided on the side of the opening 4 from the side edge 11 of the pad arm insertion hole 10. That is, the slit 12 cuts through the central portions of the peripheral wall surfaces 2b and 2d. In this embodiment, as shown in the drawing, fine irregularities 13 are provided on the surface of the pad arm 9.
[0008]
In this embodiment, the pad arm 9 is inserted into the pad arm insertion holes 10 and 10 of the peripheral wall surfaces 2b and 2d of the pad box main body 1 and the opening 4 is used for this. Insert the leg 6 of the nose pad 5 inside the pad box body 1 and pass the nose pad leg pivot screw 7 between the peripheral wall surfaces 2a and 2c. When tightened, the slits 12 and 12 are narrowed, and the pad box is inserted. The peripheral edge of the hole 10 bites into the irregularities 13 of the pad arm 9, and the pad box body 1 is fixed to the pad arm 9. On the other hand, if the nose pad leg pivot screw 7 is loosened, the widths of the slits 12 and 12 are widened, and the pad box body 1 can be slid in the vertical direction with respect to the pad arm 9. Accordingly, the nose pad main body 1 can be fixed at an arbitrary position, and the position can be freely changed after being fixed once.
[0009]
Next, a second embodiment of the pad box according to the present invention will be described with reference to FIGS. In the second embodiment, the pad arm 9 can be inserted into a position near the bottom surface 3 'of the pad box body 1' and a pair of peripheral wall surfaces 2b 'and 2d' adjacent to the bottom surface 3 '. -Arm insertion groove 14 is formed, and a slit 15 is formed in one peripheral wall surface 2b 'or 2d' in contact with the pad arm insertion groove 14 toward the opening 4. That is, the slit 15 is in a state in which the peripheral wall surface 2b 'or 2d' is cut vertically. The other parts are the same as those in the first embodiment, so the same reference numerals are given and the description is omitted.
[0010]
This second embodiment has the configuration as described above, and the pad arm 9 is inserted into the pad arm insertion groove 14 and the leg 6 of the nose pad 5 is provided inside the pad box body 1. When inserted and tightened with the nose pad leg pivot screw 7, the width of the slit 15 is narrowed, and the pad arm 9 is fixed to the pad box body 1 as in the first embodiment. On the other hand, if the nose pad leg pivot screw 7 is loosened, the engagement relationship between the pad box body 1 and the pad arm 9 is released, so that the position of the pad box body 1 relative to the pad arm 9 can be freely changed. Will be able to. In the second embodiment, since the pad arm insertion groove 14 is used instead of the pad arm insertion hole in the first embodiment, the position of the pad arm 9 is shifted to the outside, and the pad arm is inserted. -Interference between the side surfaces of the arm leg pivot screw 7 and the pad arm 9 can be prevented, and as a result, the width of the pad arm main body 1 'can be made smaller and more compact.
[0011]
【The invention's effect】
The pad box according to the present invention has the above-described configuration. By loosening or tightening the nose pad leg pivot screw, the pad box is slid with respect to the pad arm, and the nose pad There is an effect that the vertical position with respect to the spectacle frame can be freely adjusted, and the spectacles can be fitted to individual users. On the other hand, since the nose pad pivot and the pad arm are fixed at the same time by one nose pad leg pivot screw, the number of parts is the same as the conventional one, and the product cost is low. It is easy and has excellent practical value.
